How to make a Manometer, Realtime Dust Collection Filter Monitor

[Keith Outten]

This link was sent to me by Dick at Wynn Environmental. Its a DIY video about making your own Manometer that I thought might be of interest to a large number of our Members. I should disclose the fact that I don't use bags or filters in my dust collection system so I don't have any experience in this area, just thought it might be a project that might interest our Members. The project seems to be fairly simple, I have used similar commercial test tools to evaluate leakage rates of large commercial duct work systems.

Or you could just buy one for around $35 plus or minus $10. LINK

Good video, but more complicated than need be ..... Here's mine ....
A simple rubber grommet, a piece of plastic hose, and a piece of plywood
to mount it on .... I used water with black food coloring....

I think he made it complicated to include the cotton to prevent dust from clogging it. Is that not an issue?

Could you put it on the suction side rather than the exhaust side to keep it clean? Wouldn't it measure the same either way? Well, just the opposite...

I have had no issue with dust getting in the clear tubing....
I would be afraid the cotton idea might cut down on pressure,
and give a false reading ....

When I did mine, I drilled and put a fitting in the top of my Wynn filter, ran a hose (to the same board idea he used) and put in red food colouring. Not sure why the Min & Max range is needed, a clean filter will be at the min range automatically, and I drew 1/2 inch lines for reference. When the differential gets off an inch or so, it's time to check the filter.

It is simple and it works. Mounted my board right to the filter canister (because mine is mobile) and it works great.
